Hey, Napa does usually have the requisite "old guy." And, they usually enjoy doing the research. I just picked up a re-build kit for my 41 1.5 ton. The bore is also 1.25. I kinda doubt that it will work, but, the part number is 33 at Napa. If they had mine, I'm sure they will have yours. Now, any tricks to the installation? Didn't come with idiot proof instructions.
